+## Documentation Voice
+
+Use terse, normative statements. Avoid "the user wants", "currently", "now", "fixed", "regressed", "recently". State what the system **does**, not what happened.
+
+## Bullet Budget
+
+At most 120 lines per file. Nearly empty or empty files are honest.
+
+## Single-Home Rule
+
+- `architecture.md`: structural/runtime decisions (component boundaries, chosen abstractions, protocol/storage direction, explicit "X over Y" with reason).
+- `product.md`: behavior, UX, defaults, scope, naming/terminology, workflow decisions.
+- `style.md`: visual/aesthetic language, presentation/typography conventions, prose/voice rules.
+
+## Concreteness Test
+
+Every bullet must change a fresh agent's behavior. "Provide configurable, reference-compatible interactions" is delete-tier. "Status bar: powerline segments, solid right edge, inward-facing left triangle, no bold, elapsed time ≤3 chars" is keep-tier.
+
+## Exclusions
+
+- Project docs digest (already documented).
+- Global user taste not a project decision.
+- Current-task state (bugs in flight, progress, plans, TODOs, "for now").
+- File paths, line numbers, function/type names, commit/issue ids (product component vocabulary allowed).
+
+## Friction Markers
+
+A terse marker like "(recurrently regressed)" MAY close a bullet where it strengthens the instruction; keep rare.
+
+## Grouping
+
+Group bullets under short `##` domain sections. One line per bullet where possible.
